Creeping Jenny Devastation

Curmudgeon10July 19, 2011

We have (er, had) four areas of vigorous creeping jenny that has been highly satisfactory for 6 or 7 years. Yes, it must be picked and controlled to prevent spreading beyond the desired area. I do it with a string trimmer.

This Spring, for the first time ever, small catepillars starting going through the plants. We killed the critters, but even where there were no catepillars (2 of the 4 areas), the plants have just "shrunk"; the leaves are about one half or less than the size of a vigorously growing plant --- this has allowed weeds to grow, which pretty much defeats the entire purpose of a ground cover.

Does this cultivar have a "life span?" Does anyone know what might be happening? I see no alternative but to dig up these patches and start over. Ugh.

On the Perennials forum someone else mentioned this happening. I don't have any idea what it is eating them at your place.

I don't think it has a life span, but is due to the munching. It also likes moisture & prefers rich soil.

It didn't grow so well for me in the shade in one bed, but when I moved it to an area richly amended with compost in more sunshine it took off like crazy. Then I went back to that 1st bed to amend more with compost & it's covered it as well. Could be the vine weevils in that 1st bed died down. I don't know if vine weevils attack it or not, but I know there were vine weevils in the 1st bed nibbling on the rhodie & the 'Wanda' Primrose.

Maybe if you pull the weeds, add a lot of compost, it will spread again for you to fill in.
